I have a promotional offer of 5% when a combo of two products is bought together. I also offer an additional offer of 5% when the customer subscribes to the newsletter. But i want some customization in this.

The customization goes like: I do not want to allow any other shopping cart price rule when the promotional offer of 5% is allowed on cart.

I have overriden the Mage_SalesRule_Model_Validator class, but it doesnt help me.

Can anyone guide me.? Any help would be appreciated.

When creating a shopping cart price rule you have a flag called Stop further rules from processing.
Set that flag to yes and set the priority of the rule to 0 (zero). Make sure that all the other rules have the priority 1 or more and it should work without any code changes.

  • Its an extension that provides the discount on bundled products. May 26, 2015 at 14:08
  • Then you should contact the extension developer.
